Lava sand is crushed scoria, a reddish brown to black volcanic slag. It has an extremely porous texture. Lava sand makes soil nutrients more available to plant roots. It provides aeration and porosity to the soil. It helps retain the right amount of moisture in the soil and it is durable, resisting degradation.
Lava sand can be used in potting soils, bed preparation, landscape management and food crops. All you have to do to see its power is - try it!
Lava sand, compost and Azomite - a great combination.
The para-magnetism of the lava sand helps make all that happen.
Here are some of the ways to use lava sand for greater plant production.
Sick trees - broadcast under the trees at 40-80 pounds/1,000 square feet. For more effective results on sicker trees, drill 2” holes 12-18” deep throughout the root zone and fill with lava sand and compost. Any ratio is good but 80% compost, 20% lava sand is practical and economical. Lava sand is also an important part of the official Sick Tree Treatment.
Roses - add to bed preparation at 80 pounds per 1,000 square feet and to the top of roses in pots at a rate heavy enough to cover the soil surface red. Gently work into the top 1”.
Turf - broadcast at 40 pounds per 1,000 square feet. Mix into topdressing at 20% of the volume.
Bed preparation - till together with compost, dry molasses, whole ground cornmeal, Azomite and natural organic fertilizer. Use 40-80 pounds per 1,000 square feet.
Potting soil - add up to 1/3 the volume of organic potting soil.
